Constitution Article 5 Section 9
Section 9[edit]
All regular members employed by the Postal Service shall be entitled to ratify or reject by majority vote national contracts or parts thereof tentatively agreed to through negotiations prior to expiration of existing contracts in accordance with procedures published by the National Executive Board in a timely fashion prior to ratification. Members shall be furnished with the text of any proposed changes and deletions together with their ballots. The outcome of the membership referendum shall be binding. The fundamental commitment of this Union to membership ratification of national contracts requires that the timetable of negotiations will be arranged to ensure a binding referendum on tentatively agreed‐upon national contracts or parts thereof reached prior to expiration of existing agreements.
